Enum IsleConstructor

pub enum IsleConstructor {
    RetMemorySideEffect,
    RetGpr,
    RetXmm,
}

Different kinds of ISLE constructors generated for a particular instruction.

One instruction may generate a single constructor or multiple constructors. For example an instruction that writes its result to a register will generate only a single constructor. An instruction where the destination read/write operand is GprMem will generate two constructors though, one for memory and one for in registers.

Variants

RetMemorySideEffect

This constructor only produces a side effect, meaning that the instruction does not produce results in registers. This may produce a result in memory, however.

RetGpr

This constructor produces a Gpr value, meaning that it will write the result to a Gpr.

RetXmm

This constructor produces an Xmm value, meaning that it will write the result to an Xmm.

Implementations

impl IsleConstructor

pub fn result_ty(&self) -> &'static str

Returns the result type, in ISLE, that this constructor generates.

pub fn conversion_constructor(&self) -> &'static str

Returns the constructor used to convert an AssemblerOutput into the type returned by Self::result_ty.

pub fn suffix(&self) -> &'static str

Returns the suffix used in the ISLE constructor name.
